USB hid-keyboard example "Device Suspended" and "USB HID device is not ready"

[srubin-nottinghamspirk]

Hello. I have been playing with the HID keyboard example (./samples/subsys/usb/hid-keyboard) and it's not running correctly. Here is the output from the terminal:

*** Booting Zephyr OS build v4.0.0-1487-g595d81a941c5 ***
[00:00:00.010,000] <inf> main: HID keyboard sample is initialized
[00:00:00.016,000] <inf> main: USBD message: Device suspended
[00:02:48.895,000] <inf> main: USB HID device is not ready
[00:02:49.090,000] <inf> main: USB HID device is not ready

The two "USB HID device is not ready" messages come after I press the user button.

I get the same response on both an STM32 "blue pill" (-b stm32_min_dev) and STM32 "Discovery kit for IoT node with STM32U5 series" board (-b b_u585i_iot02a). The results are the same on two different host Windows computers. Results are also the same forwarding the USB device to WSL with USBIPD.

Has anyone else run this example recently?

Any ideas?

Thank you!
